WATCH: Khloé Kardashian Says It’s ‘F*cked Up’ Rob Kardashian Proposed to Blac Chyna

Kendall Jenner Yells at Rob Kardashian
"Rob is dating someone that has kind of had a bad history with my family."

Though things between Rob Kardashian and his sisters are a bit better now, that has not always been the case.

In a new teaser for the upcoming Season 12 of Keeping Up with the Kardashians, Rob explodes on his siblings upon learning that older sis Khloé Kardashian said that it was “fucked up” he proposed to Blac Chyna in front of her whole family just months after they started dating.

“The fact that he now wants to be so public blows my minds,” Khloé says of Rob, who became reclusive during the past few years and was absent from their reality show last season. She then tells sister Kourtney Kardashian in another scene, “He proposed in front of her whole family. That’s so fucked up!”

“You make sure your girlfriend doesn’t publicly bash your sisters,” Kim Kardashian tells Rob on the phone as Kylie Jenner, who is dating the father of Chyna’ son, looks on in concern.

“Listen to the hostility in your voice. This is exactly why I don’t say anything,” Rob tells his three older sisters. “[This is] the first time I ever proposed to someone in my life. Don’t come at me with some bullshit!”

In a previous preview, Khloé and Kim both urged their mother, Kris Jenner, to stop paying for the house that Rob and Chyna currently reside. Like Rob, Kris got defensive and called out the girls for ganging up on their sibling when he’s trying to get his life together.

Clearly, there’s still a lot of drama in this family.
